 everywhere!. NW. Iceland: Sugandafjordiir'; Isafjordur!; Armuli!; Arn- 

 gcrdarcyri!. W. Iceland : Brattabrekka I. S. Iceland: Barkarstadr!, 550 

 metres above sea-level. 



Grows on damp boggy ground, almost alvvays mixed with other 

 mosses such as Hypnaceæ, Cinclidiiwh Mccsia trichoides, Dichodontiiiin 

 and Bryiim ventricosiim. In N. Iceland, where it is most widely distri- 

 buted, it extends from tlie lowlands to a height of upwards of 600 

 metres above sea-level. Thus, near Husavik, it was very common in 

 Hypniim bogs, and near Akureyri it was found especially in bogs at an 

 altitude of 500—600 metres. Near Seydisfjordur it was common from 

 about 100 metres upwards to the mountain heights. From the soutb- 

 western and southern part of tbe country it appears to be absent, or 

 is at any rate very rare; it was found in this part of tlic country only 

 in a Hypnum bog near Barkarstadr, at an altitude of 530 metres.

Occurs liere and there all over the country, but as a rule only in 

 single tufts on the bodies of dead animals. Near Djupivogur a large 

 tuft was found on a rotten Hsh. 



The fruit, which occurs abundantly everywhere, ripens at the end 

 of June. 



111. Splachnum sphæricum (L. fil.) Swartz. 

 Splachniun pedunciilatiim Huds.) Lindb. 



Iceland (^Morch)!; commonly distributcd 1. 



Grows on cow-dung in wet, marshy ground, often mixed with S. vas- 

 cnlosiim, but is less frequent than the latter. It occurs most frequently 

 in North Iceland and also, to a certain extent, in East Iceland Seydis- 

 Ijordur and Vallanes). where it is met with abundantly in many localities, 

 it is somewhat rarer in South and South-west Iceland and probably 

 does not ascend higher than 300—400 metres above sea4evel. 



The fruit ripens rather irregularly, so that in the same tuft both 

 ripe and also ([uite young cajjsules may be found. The majority of the
